Person Re‐identification Based on Feature Erasure and Diverse Feature Learning
IET Computer Vision, 2022 Robust and comprehensive modelling of targets is the key to successful person re‐identification. However, some useful information may be ignored, since CNNs tend to learn from the most distinctive feature region of the human body. In the present study, a

Characterizing Fabric Anisotropy of Air-Pluviated Sands [PDF]
E3S Web of Conferences, 2019 Sand particles depositing through air generally align their largest dimensions in horizontal plane, forming a cross anisotropic fabric. Therefore, sands display varying strength, permeability, compressibility with directions.

Metallicities of Globular Clusters m3 and m5 from VI CCD Photometry [PDF]
Journal of Astronomy and Space Sciences, 2000 To derive the metallicities of M3 and M5, we used the shape of red giant branch, horizontal branch magnitude, and red giant branch bump on the (V - I) - V color magnitude diagrams.

The strange hot horizontal-branch binary star in NGC 6752
Open Astronomy, 2018 M5865 is the only so-far confirmed close binary found in the extreme horizontal branch (EHB) of a globular cluster. A detailed study has recently proposed that this object could be a close system (period P=1.61 days) comprising a EHB and a main-sequence ...

On the red giant branch mass loss in 47 Tucanae: Constraints from the horizontal branch morphology [PDF]
, 2016 We obtain stringent constraints on the actual efficiency of mass loss for red giant branch stars in the Galactic globular cluster 47 Tuc, by comparing synthetic modeling based on stellar evolution tracks with the observed distribution of stars along the ...
